Sensor.Community E-Paper Data Display

It is a simple app to get data from an AirRohr sensor and display it in a very simple fashion on a Sha2017 e-paper badge.

The app assumes that you have a dustsensor + environmental sensor with two consecutive sensor-ids.

Pull-Requests welcome. Project is currently evolving on GitHub


  1. connect your badge via USB
  2. open the serial console to the badge
  3. start the python console
  4. set the sensor id of airquality-dust-sensor that you want to query:
    import badge
    you can get the sensor-id from the map or by logging in to Click data of your sensor and use the particulate matter sensor ID.
  5. quit the python console
